What happens if a ParNew is triggered while CMS is running? Will it wait
for the CMS to finish? If so, that would be the eplanation of our long

Hi Sylvain,
I applied the patch to the cassandra-2.0 branch (this required some manual
work since I could not figure out which commit it was supposed to apply
for, and it did not apply to the head of cassandra-2.0).

My bad; should have checked the code:
/**
* This function executes local and remote reads, and blocks for the
results:
*
* 1. Get the replica locations, sorted by response time according to the
snitch
* 2. Send a data request to the closest replica, and digest requests
The main issue is that cassandra has two of everything. Two access apis,
two meta data systems, and two groups of users.
Those groups of users using the original systems thrift, cfmetadata, and
following the advice of three years ago have been labled obsolete (did you

Sylvain,
I am trying ccm to install and it does from source directory, I have tried
2.0.4/3/2/1 and 1.2.15, all of them are reporting the same failure after

I am using 1.56.34 and 1.56.38 client both reports the same issue.

I am using CCM to install the servers, it is bringing in the source code,
is there any option for CCM which I can set only to download the binary,
just to make sure it is not bringing in the working copy of the code.
